Question about Dremel Variable - Speed Multipro Rotary Tool 395
Collett holder appears to be a press fit onto armature shaft, worn bearing is behind holder. How do I remove holder to get to bearing?
You can put new grease into that bearing without removing it by following the steps in this M.S. Paint drawing I made. After a bit of protest, mine started running a lot better.

Electrically speaking there are a few items to check.
1) The easiest is to remove the two brush holders screws on each side by the power cord. If one of the screws are loose, or the bushes are worn you will get intermittent or no operation.
2) Second use a volt ohm meter to make sure you have voltage on the two brush connectors inside the brush holders when power is on. If you do then open the unit a check continuity on the motor armature to see if it is open, which will cost $13.37. If you do not have voltage, inspect the power cord and switch.
